Any Android Apps that can record internal audio?

I have a Nvidia Shield in which I use Shou Video Recording to record my gameplay or what i'm doing(similar to capture cards)

The Issue is that the App doesn't allow direct audio recording from the shield, and the closest thing would be the "Mic option"(which unfortunately records the sound of my button presses as well)

So I was wondering, is there a separate app that can record audio directly from the shield, or any android device?without worrying about any noise from the background? As well as recording from the background of the Android phone? Meaning if I'm playing a game, the app will still be internal audio recording the games sound.
